Alarm ID Alarm Severity Alarm Type

Impact on the System

Insufficient power supply on the port may cause low-priority PDs to be automatically powered off.

Possible Causes

The power of the PD connected to the port increases sharply.


  1. Run the display poe power port { port-num | all } command to check the maximum power configured for the specified port.
  2. Run the display poe-power command to check the total power of PDs connected to all ports.
  3. Perform the following steps as required:

    • If the maximum output power configured for the port is smaller than the total power required by the PDs and can be increased, run the poe power port port-num port-power-max command to increase the maximum output power. Ensure that the output power is sufficient for all the PDs.

    • If the maximum output power configured for the port is smaller than the total power required by the PDs but cannot be increased, run the poe priority { critical | high | low } port port-num command to set power supply priorities for PDs. Then low-priority PDs are powered off and power supply of high-priority PDs is ensured.
